Garmin Forerunner 955/955LTE – What features will we see?

This is a significant revision of content from May 2019

Return to Garmin Forerunner 955 Review

Jabra Elite 85t Review SpecificationsWhilst it’s a secret in Garmin’s head office, it’s almost certainly no secret to regular readers that we’ll see a replacement 945LTE in 2021, rumours say as soon as Q1, although my personal bet would be later.

This article looks in detail at what features & specifications might be in the Forerunner 955 and any LTE variant of the 955 or 945.

More Info: What to expect on Garmin Forerunner 955 (FR955)

We can expect some goodies by looking at how quickly Garmin introduced new features to catch up with those introduced by competitors. When Garmin have been outmanoeuvred they react swiftly eg to the novel TRACK feature introduced by Coros. Thus with other new features on the ELEMNT RIVAL triathlon watch and Polar Vantage 2, we might see them copied and improved for the 955. I’m specifically thinking of the Wahoo’s auto-transition feature, let’s come back to that in a minute.

Don’t be distracted by the unimaginative Garmin Forerunner 745 (aka 945s), which was disappointing with a similar price & features to the ‘ageing’ Forerunner 945.

Instead, what is impressive are the new features that have already found their way into the 945 over the last 18 months (list of new features) which include Daily Suggested Workouts, Track Mode, Improved Recovery Calc, FE-C Control, UI improvements like in-place data field editing, virtual run activity profile, respiration features, swim features, PacePro and oHR for swimming. Even with my critical hat on I would have to say that is an impressive list of new features. Oh and don’t forget the 745 had GPS accuracy improvements and recently we saw new beta firmware include further tweaks to the GPS firmware – which might bode well for better performance from the 945 too.

Current State-of-Play

The Forerunner 945 might, to all intents and purposes, seem like a Fenix 5t Plus – ie it appears to be highly similar to the Fenix 5 Plus range but with a lightweight plastic shell for triathlon. Yet that is unfair as there were additional hardware boosts (Sony GNSS, ELEVATE v3) and there are UI improvements too. The point of mentioning this is that the 955 will play hardware catch up to the 945 and bring in features from the existing Fenix 6 plus, probably, one major, new headline feature.

We expect a Forerunner 955 and Forerunner 955 LTE. The 955 LTE might instead be called the 955 PRO.

Form & Overall Function

The Garmin Forerunner 945 is a premium multi-sport watch and a derivative of the Fenix line.

The large, medium, small and lightweight, circular formats are here to stay with the Fenix in both Pro and non-Pro versions. The FR945 is effectively a medium format PRO version and the FR745 is a small format, non-pro version. The FR955 will be the same format ‘plastic’ watch as the 945.

The Fenix format is extended to sport-specific models such as Descent (dive), Tactix (military/hunting), Delta (aviation), Forerunner 9×5 (triathlon) and these are each refined with a luxury MARQ version which has a premium case. To some extent, kinda, there are entry-level/lower-level versions of the Fenix (INSTINCT) and FR 945 (FR 735/745XT) and we can expect those lower-end models to continue or even appear as new products to cover military/aviation/driving/diving uses if there is a significantly larger market for them (I don’t think there is).

The existing Fenix button layout/ hardware interface works well and will not change significantly. However, the software user interface is clearly improving as we have seen with the 945 and Edge 530/830.

It’s possible a touchscreen with optional enablement could be introduced on one of the future models but I hope not. The optional touchscreen does work well on the Suunto models for out-of-sport usage.

Weights and dimensions will be slightly changed by a subtly different battery and other components.

Take Out: Incremental change to the hardware, possibly significant changes to the software UI. Unlikely we will see multiple variants of 955 (Solar), other than the LTE/PRO version.

Cellular Connectivity

An ‘obvious’ market trend for Garmin to follow would be for the high-end of the Fenix/Forerunner ranges to have onboard cellular connectivity like the Vivoactive LTE. Whilst this might let you take and receive phone calls on the watch, perhaps the more important feature is 24×7 data connectivity. So we are NOT talking here about taking a call in the middle of your triathlon but rather having GROUP TRACK and LIVE TRACK enabled in your triathlon…without a smartphone. We are also talking about over-the-air streaming music services and very many other location-based services like ASSISTANCE that already exist for your smartphone.

Take Out: A variant of the 955 and 945 are already leaked to have cellular connectivity and this will be the HEADLINE FEATURE for the announcement.

Garmin Forerunner 945 ReviewMusic

Music support has shown its pretty head in with the Forerunner 945

I could slate Garmin’s implementation of Music in OH SO MANY WAYS. However, the reality is that, for sports usage, it’s superior to everyone else. So, such criticism would be unfair and I’ll be nice. AFAIK Garmin’s platform is ready for Google and Apple to integrate their music services if they want to. I can’t see Apple doing that (you never know) but I DO expect YouTube Music/Google Play Music to come to the 955 in 2021. But what is happening here with Google is highly strange as iOS & WatchOS versions of Youtube Music have been released but there is no version at all for Wear OS. Very strange.

The inclusion of LTE will enable live music to be streamed when you are running rather than stream-and-cached to your 945 over WiFi. That’s a headline for some.

AFAIK no smartwatch has a high definition playback codec like AptX HD and I don’t expect the 955 to have that either.

Take Out: Proper streaming on the 955 LTE with YouTube Music to follow.

Garmin Forerunner 945 ReviewContactless Payment

I’ve not followed this too closely but it looks like Garmin’s global adoption of new banks has slowed recently.

As contactless payments make their way down to Garmin’s lower models and transaction volumes increase then Garmin will be a more important source of revenue for the banks and Garmin Pay will become more important to Garmin. Hence the take-on of new banks will continue, albeit slowly.

Don’t expect to see Garmin support a payment provider like ‘Generic Visa’. Apple and Google can and do that. Garmin likely won’t or can’t.

Take Out: Same old, same old.

Garmin Forerunner 945 ReviewOptical Heart Rate

Version 4 of ELEVATE is the go-to, new oHR sensor for Garmin in 2022. It will be on the 955/955LTE and most other models like the Fenix 7/Epix 2 with an outside chance of a few spares ones being used on the Instinct 2 in early 2022!.

Take Out: The current ELEVATE v3 will be on the 955.

GNSS: GPS, Galileo & SBAS (GLONASS, GPS 3 and BDS too), L1/L2/L5(a)

Dual Band GNSS with GPS+GALILEO is already in the 945

Garmin recently got GPS+GLONASS to an optimal state with the Sony chipset, that wasn’t a great state so it was time to change suppliers to Airoha/MediaTek.

Dual Frequency (L1, L2 or L5) plus Dual Band (Glonass, Galileo) is not possible on the existing Sony chipset for the 945 but it is possible on the next generation which Garmin started to use in September 2020. and on the Airoha chipset that the Fenix 7/Epix uses.

Take Out: GNSS improvements will be promised from the new Airoha sensor

Onboard Sensors & 3rd Party Sensor Support

I think we are pretty much ‘there’ with 3rd party sensor support for the Garmin Forerunner 945. The recent sensor Hub improvements seem to make for generally better connections in my experience, but still with the occasional annoyance.

With the arrival of the HRM-PRO, all major Garmin sensors except the running pods & tempe now broadcast in ANT+ and BLE.

Garmin might make a physical pod that is a STRYD competitor but is far more likely to introduce a wrist-based calculation of running power.

Garmin already has the ability to accept new data types through CIQ. So if we ever get a decent hydration sensor (like Aura) or a blood glucose sensor like Libre then it will slot into your Fenix 6/955 relatively easily. Let’s face it, it will even slot into the older tech easily enough. (Note as of Jan 2021, the ANT+ spec IS being extended but I only know that the extension at least includes BODY/CORE temperature)

I hope we will see something ‘sensed’ by ELEVATE v4 in addition to SpO2 (like hydration) but that’s for the Fenix 7.

Take Out: Uncertain if we will see new BLE-enabled pods to replace Tempe, RD and the running pod.

Garmin Forerunner 945 935

Screen Size & Resolution

Let’s start off with the easy one. The Fenix 6 kept the same case size as previous models but introduced a larger usable screen area by making the bezel are smaller. It’s highly likely that the Forerunner 955 will have this same larger screen area enabling the support of more data fields and/or larger fonts.

Whilst LOTS OF FEATURES plus GREAT BATTERY LIFE = SUCCESS for Garmin, the hardware drawback has been a relatively poor screen which in my eyes makes me wonder why anyone would buy the MARQ when the screen looks like how it does…ie it looks poor as a 24×7 watch face.

The existing Forerunner 945 screen resolutions and colours are not much changed from earlier Garmin models and they fall WAY behind the resolution, brilliance and vibrancy of many of the more mainstream watches (Apple Watch, WearOS watches).

The screen is one of the key compromises Garmin has had to make. Garmin could quite easily introduce an amazing AMOLED screen but BANG would go the battery life and then athletes would start complaining.

IMPORTANT POINT: This necessary (and correct) compromise that Garmin made historically is now at the crossroads. We’ve already seen, from several of the new feature sets discussed above, that Garmin is getting into the 247 world. And to do that the screens absolutely 100% need to significantly improve to support 247 wearability. We will see that at some point in the future with the Fenix/top-end Forerunner products once Vivoactive has it.

Take Out: The 955 will get a bigger screen but it will be the same tech we already have behind it.


Something has gone wrong with the latest generation of Garmin batteries. The headline figures look awesome but the reality is different. Indeed, the recent FR745 had significantly downgraded battery performance. I suspect that the battery is highly similar to that in the 945 but Garmin has scaled back or clarified its claims somewhat.

Fenix 7 sees big improvements in battery performance and further improvements with the solar models.

Take out: 955 will mirror the improvements of the Fenix 7

New Features

You can only slice and dice data in so many ways. However, I think there is still quite a bit of scope for Garmin to think harder about what they do with positional and accelerometer data. With a little more thought, they might come up with things like this that might even be USEFUL


The thing is, Wahoo must read this site and not Garmin. Following on from the original version of this post over a year ago, Wahoo has introduced two new transition-related features in their Wahoo ELEMNT RIVAL sports watch.

Garmin is CLEARLY already planning something similar as the MARQ Athlete was launched with stated support from auto-transition in SwimRun events. However, IIRC,  that feature appeared on Garmin’s website but never made it to the watch. Almost two years on do you think Garmin has ironed out any bugs? A: Yes 😉

Take Out: Only expect to see one MAJOR new software feature in the 955 at launch. Maybe that’s the native running power or maybe that’s more triathlon features like auto-transition. Both will come just not at the same time.

Transition Dynamics

OK, this is just a fancy way of actually measuring how long you stand still to change your clothes. You uber-competitive types could also use this first thing in the morning 😉

Clearly, you can’t compare T1 times from one race to another as the distances vary each time. But the time taken within T1/T2 to find your racking position, get changed and head off should be able to be relatively easily estimated by accelerometers.

If someone at Garmin HQ wanted to get clever they could even guess in what order you changed your items of clothing in transition.

Perhaps we will see a metric for ‘stationary time’ during transition?

Take Out: nah

Garmin Forerunner 945 ReviewRace Intelligence – Performance Tracking

Garmin introduced Livetrack 2.0 in August 2020. which included references and features linked to Event Sharing.

Once we get LTE on the 945 then there’s no reason why Group Track and Live Track can’t be FURTHER extended to sensibly broadcast more detailed stats during a race eg 10-minute bike power splits, or whatever. But the beauty here is that these stats will eventually be combined online with everyone else who is doing the same race at the same time. Maybe that’s for your own interest or for the benefit of your coach to give in-race feedback (probably against the rules).

For this to work there needs to be some definition of what an ‘event’ is and for people to sign up to digital data sharing for it. I can’t see Garmin doing that so let’s see if anyone in Silicon Valley is listening.

Even if getting a true leaderboard might be difficult, as not everyone will share data, there would still be scope to compare certain elements of your performance against others on the same day in the same conditions and those kinds of comparative race-day stats will be of value to those who see themselves as wanting to get faster in some way.

There are issues around spotting cheats and anonymising data but such data is the sort of thing we clamour for from the pros so let’s start off with the amateurs doing it.

With tens of thousands of UK parkrunners ‘racing’ each week and tens of thousands of athletes at the well-known mass-participation events, there really are quite a lot of people that could use race-based tracking intelligence.

I guess you could apply similar competitive stats around your Group Track Sunday bike rides and the like.

Take out: There is a reasonable chance that we will see an extension of the existing broadcast of personal performance metrics. However, it will probably take a 3rd party  to provide a platform to start sharing such data

Race Location – Intelligence

If I go to my local pool or local race track then there is scope for the site’s GPS location to automatically give me pool length, lap length and/or startline position, assuming that Garmin knows the location & size of every pool and race track. In the former case, the pool length is known and in the case of races the course route and key lap points might be known eg, there is a database of motor racing circuits that I believe the MARQ Driver uses.

Location intelligence could have nice training benefits such as saving me having to set my pool length 3 times a week as there are 50m, 25m and 36m pools that I use.

Race Track – If your end-of-lap location is known (ie the finish line) and if you are using your Forerunner 955 over LTE then laps can be automatically added based on location and your last lap’s worth of performance stats can be piped up to the net for all to see

I’ve been known to do the Hillingdon 10 mile TT (closed circuit), it’s amazing how hard it is to count 11 laps and it would be nice if Garmin could do it automatically. I’m thinking of some way of automating lap counting – clearly, I could do something based on total distance travelled and I believe there are location pods that a race organiser could very cheaply deploy at the start line.

Take out: A nice-to-have that’s probably expensive or tricky to implement, so it won’t happen.

True Laps

If you run 1km intervals that are 980m or 1010m then it’s just that little bit annoying that the watch hasn’t recognised the TRUE effort+duration. It’s not that the 10m or 20m more/less than I intended makes any difference physiologically it’s because the recorded lap will have incorrectly averaged data eg if you stop a couple of metres or seconds too early then the lap average stats become wrong and it becomes hard to compare your lap-on-lap efforts when you later analyse your stats. It would be much easier if the lap could be determined based on effort/power/speed ie once the power drops then take an automatic lap either in real-time or modified once the workout has finished.

Cyclists with power meters know that after a while it’s all about power-duration. I certainly now look much more at power-durations than power averages for a lap.

Golden Cheetah is able to auto-identify effort periods by analysing the workout, so the maths are out there and known and probably somewhere on GitHub. The difficulty with implementing this type of functionality is that there can be multiple layers of ‘true laps’ of different time periods that overlap each other. It’s difficult to explain quickly here but some clever person at Garmin could figure it out easily enough.

Take Out: maybe

True Climbs

Since the original version of this post was published we’ve seen some activity in this area by competitors eg Polar’s Hill Splitter.

Rather than looking at effort for the True laps of the previous section, we could also look at grade to create laps that match climbs – fit file repair tool can do this post-workout ie the start and end of a physical lap are the start and end of a climb. This will overlap with some elements of ClimbPRO and STRAVA segments but I think it is different.

Take out: probably not from Garmin.

Auto Performance Alerting

This is different to being alerted to exceeding a pre-defined performance criterion. It’s more about that criterion being dynamic and changing based on performance.

Whilst automatic gear selection based on power is probably a gadget too far, a nice CIQ app would tell you that you are a couple of cogs away from optimal. There are similar things to this already out there – for example, a XERT’s free CIQ app suggests optimal cadence for the current effort level.

Special, dynamic, alerts could be introduced to warn you of detrimental performance. eg sprinting for the first 200m of a 5k race at your 800m pace might signal an ‘irrational exuberance alert”

Take out: nah

Voice Control

“OK Garmin, take a lap”

One day this will happen. Hopefully not too soon. I talked about this in more details recently (here).

Having said that I do use ‘OK Google’ a fair bit at home and whenever I’m using a WearOS watch I will sometimes use that rather than one of the house’s WiFi Speakers/Mics. I’d probably use ‘OK Garmin’ on my 955 if I’m sadly honest but I certainly would never admit to that 😉

Sometimes I faff around trying to remember which earbud to press to skip some errant song that has appeared on my playlist when in mid-run. I can never quite remember which earbud it is that I need to press and then inevitably turn them both off. ‘OK Garmin skip track’ might be a nicer and more elegant solution for me. Sorry, I now realise I have lost what little serious sports credibility I once imagined I had 😉 .

You get the point tho. Someone somewhere will use it both for in-sport functionality as well as for controlling smart homes and just generally querying the net. In the link at the start of this section, there is a little more discussion around voice-enabled navigation which is a valid use of voice tech in sports watches.

Take Out: Hold your breath, it might come. Take a DEEP breath. But it won’t be there at launch, maybe 2023? If ever.

Running Power Integration

Rather than a new pod, it’s more likely that we will see Garmin introduce running power calculated on the wrist without a pod coupled with an introduction of full platform support for native running power.

Running power data is currently incorporated into the Garmin data environment via CIQ. So running power is DIFFERENT from cycling power and running pace and heart rate and everything else. That’s why, for example, you can’t currently get native Running Power Alerts. Running Power doesn’t ‘plug in’ in quite the same way. Worst still, Garmin running power and STRYD running power are different buckets of data and based on different algorithms and based on different source sensor data.

Take Out: Yep. 2022 Baby!

Intelligent Training: Firstbeat, Xert and more

When this article was first written I didn’t imagine that Garmin would buy Firstbeat. But they did and then they release Daily Suggested Workouts which is exactly the Intelligent Training I had hoped for and which has been rolled out from bike-only training on the recent Edges to now include running suggestions.

However, there is still more to come here. Intelligent Training is perhaps the major area where much remains to be exploited and it’s an area where the technology and formulae already exist. It’s ‘just’ a case of someone, somewhere writing all the correct and clever bits of code to make it happen. I’d class intelligent training as covering things like adaptive training plans (macro); adaptive workouts (micro); and real-time, intelligent audio coaching feedback.

Learning from your historic workout patterns (for rest and long run days) and then trying to hit a workout TE goal is ‘very 2018’. Intelligently adapted micro workouts would look at AnTE, AeTE, HRV and consideration like Xert’s MPA and micro recovery algorithms. See! I told you it wasn’t easy. Garmin is still doing the 2018 stuff…most other people are behind that.

Take Out: These features will be expanded by Garmin over time.

Garmin Forerunner 945 ReviewNavigation

Navigation via TOPO maps is included in the current Fenix series – 945, 5 Plus, 5S Plus, 5X Plus, MARQ, 6.

The 945 already has a DEM database of the elevation of GNSS points

You can only get from A to B in so many ways. They are already pretty much ‘invented’ and ‘out there’.

The future will be about the intelligence and functionality built into geographic points rather than how to get to them…we already know how to get somewhere ‘easily’ enough augmented by clever things like popularity routing. I also seem to remember reading somewhere that bike/hike routing has been implemented by a Garmin competitor that finds routes that minimise the elevation gain.

One of the cumbersome things when using the 945 to navigate is actually instructing the 945 how to navigate when in the middle of nowhere. The 5-button interface is really not great for this except in an emergency when no-one in your group has a smartphone. Referring to an earlier point, the voice enablement for navigation could be useful, working along similar lines to the voice-enabled navigation features of Google Maps. Just sayin’ ;-).

“OK Garmin, navigate back to start as quickly as possible”

Take Out: Navigation is Garmin’s thing. Improvements will always come



Thoughts and votes welcomed…This is an old poll with 3300 votes for improvements that readers wanted from the 935. It’s worth seeing what was wanted then…and still not delivered upon.

31 thoughts on “archive ❌ Garmin Forerunner 955 / 945LTE /PRO – new features – likely & unlikely ones, discussion, speculation

  1. What about build quality? It will remain all plastic or it will get some kind of metalic bezel like 645 had ?

    What do You think ?

    1. To be fair the 935/945’s “plastic” (fibre-reinforced polymer) is pretty sturdy, with a premium feel, and nothing like the cheap stuff used in other plastic watches (like the 735 or other Garmins pre x45, or Polar M200, Pace 2). This material is favourable to metal in every way.

      1. I have a different opinion about premium quality. My brand new FR745 gives the same toy feeling like any of my previous Garmins. The five buttons work in at least three different ways. Like before. I hope other design issues will not occur on this (e.g., button stuck, oHR crack, white spot on display).

        I would be willing to pay a premium for better build quality. But Fenix is a brick on my wrist.

  2. Thanks for the overview of what the high-end of the FR line is like. I’d like to think the FR team will have lunch with the Approach & Descent guys so there is more depth in the accessory side of things. Agreed many runners only want to go out with their watch and clothing. I don’t know that LTE alone would be enough to get me to upgrade from the FR945.

    1. agreed.
      bigger screen is enough for me as I like it on the f6 and hopefully clarity on the real battery life will come too
      i would hope new features, like native running power, would be rolled back to the 945. but native running power would make me upgrade.
      actually i’d probably get the 955lte to try out lte as well. just for the fun of it!

      who am I kidding? i’d just get the 955 for the different number 😉

  3. Stryd have been teasing that some un-yet spoken of feature will be released with the 955.

    Everything you mention about the 955 sounds good, but other than native run power (awesome) they’re minimal wow factor for me. (yes, I’m a grumpy middle aged man)

    Nevertheless I am very much looking forward to its release.

  4. Sigh so my brand new 945 is aging already 🙁 Think I’ll be holding out for the 975/985 as a replacement, who knows what they might do.

      1. It’ll look at your FTP/CP and the race prediction will be so accurate there will be no need to race, the results will already be known. No more virtual racing for me – just sit on the sofa and cry about my lowly CP.

      2. it gets better. FTP/CP is affected by fatigue so to achieve a sofa-PB you just need to taper into it, perhaps just sitting there for 2 days before awarding yourself the PB should do it?
        (I know Will knows this but for anyone else, look at Xert’s MPA to see why ftp is ‘wrong’)

  5. I’m expecting some sort of next interpretation for their solar tech to improve on battery life

  6. Honestly, gps accuracy will be a game changer for most of the people. Just getting this instant running pace accurate would be great.

    1. #stryd.
      i dont think it will happen with the current tech. even the dual frequency/dual band stuff I don’t think will give instant pace accuracy in less than ideal GPS conditions (in ideal GPS condition its pretty good now)
      i think for you and me accuracy is important and you can see form the results in the poll above there are quite a few people who also want it. I’ve come to the conclusion that the significant majority of people don’t really care about accuracy or don’t realise what they have is inaccurate. #shrug
      sorry to put a damper on things 🙁 I hope I’m wrong

      1. It is? Even on trails? I am hesistant to buy something that needs to be swapped to one of my more than 10 running shoes that I currently use.
        Something like a wearable add-on GPS enchancer would be something I would consider.

      2. you have to take it off to charge it in any case.
        changing stryd from one pair of shoes to another must take 10 seconds, tops?

  7. Do you think they would put any kind of enhanced LED display like the AMOLED on the Venu in to the 955? thanks for this – great read btw!. Any more suspicions on when this will be released?

  8. Having lost my trusty FR935 to a nasty wave in the Caribean (yes, life is hard) courtesy of a QuickFit bracelet…I no longer have a good reason not to upgrade to the upcoming FR955, be it LTE or not, can’t wait actually ! LTE sounds good on paper but that means Garmin would have to strike agreement with carriers in Europe for eSIM implementations, they didn’t bother for the Vivoactive did they…
    A nice screen like on my Polar Ignite wouldn’t hurt as I don’t need humongous battery life but I may be in the minority. I suppose I could use ClimbPro too…Come to think of it the 945 might be enough for my “needs” 😉

  9. Many Thanks for your great work. Will you Update this Articel? Are there any news to the Release Date?

  10. The Forerunner 945 has almost all the features of the Fenix 6, it’s a bit inaccurate to say it’s like a Fenix 5.

    1. it’s like the F5plus from hardware point of view (not identical eg Sony chip) with some MARQ features thrown in.
      935 was like the f5
      F5Plus released june 2018, FR945 released on May 2019, fenix 6 released Aug 2019. f6 is the flagship.
      the 955 was always going to be the plastic fenix 6…that still hasn’t come.

      1. I was going by the awesome compare feature on the Garmin website where you could show only differences. The only featureset I saw different between the F6 and the 945 was a couple of the golf features, everything else like pulse ox, body battery, the additional training effect features, mountain bike grit and flow are all the same between the F6 and 945 and missing on the F5 and F5+.

  11. Another future upcoming feature might be more precise nutrition estimations based on heart rate, HRV, maybe even planned workouts/trackprofiles?

    I’m not just talking about carbs, proteins and fats, but about vitamins, minerals and aminoacids.

    There already exists an app:
    Cronometer, which can be synced with polar (only calories and sleep are synced at the moment).

    But what I really would like to see is a non-bloody possibility to measure lactate.

    1. hi
      yes polar also has the fuelwise feature but, like Garmin, they are essentially INaccurate as they are based on heart rate and hr zones.
      i think the micros are too niche for garmin to do and, again, it would not be accurate if based on HR

      Cronometer looks good but too generic for athletes

      lactate detection will come from oHR. maybe in 2-4 years time.

      there is the existing supersapiens integration of course for glucose and moxy for muscle oxygen.
